Really annoying that they're not publishing the new prices now, we have to wait until 1st September.
The new prices for the colocation electricity/air conditioning rates are:
electricity/air conditioning rate old price\* new price\*
Germany € 0.29/kWh € 0.45/kWh
Finland € 0.12/kWh € 0.22/kWh
\*These prices do not include VAT. The products that do not directly use electricity are not affected: IPs, domains, SSL certificates, racks, setup fees, and a few other examples.
